I can see the value in it for some other plants, but for bananas they need to be tissue cultured in some way prior to putting them into the photoautotropic system. For bananas, it seems that if you made it that far then you are at the point where you could also just put them into soil and grow them without any more lab work. Even in the paper by Kozai, it states the bananas were cultured on MS media prior to induction into the photoautotrophic system. For example, just today I transferred 36 banana explants (Senorita for those curious) from TC vessels to soil where they will continue growth into normal plants (on my dorm room window sill no less, haha), as I understand it, this is the stage at which you could also transfer to the photoautotrophic system if you wanted them to grow faster after culturing I suppose.
